If you hear one scrwam or you just hear battle music flare up out of nowhere, dismount IMMEDIATELY. They can only stun you while you're on your mount so if you get off before it reaches you it won't stun you when they hit. Its much better to be off your mount for a bit during a battle rather than being stunned AND dismounted in the middle of a battle.
Be ware!, they are the best kicker of all ARK. Imagine they hit your head with their super tiny leg, and surprisingly, with its power, they can knock u off from your mount and stunt both of you easily. Thats the power of the chiken leg
Oh yeah, dont forget with their massive scream. If you translate it, they say " u expecting an archeo, but its me MICRO!!! ORA!ORA!ORA!ORA!"
I hate these bastards with a burning passion. They have knocked me off my mount so many times in the red woods, get my health down while I’m stunned and then some Carno or terror bird comes over and finishes me off. They will kill you, your family and anything you have ever loved.
I keep confusing these things for archaeopteryx and dimorphs. One will flee in fear and climb onto the trees, one won’t react at all unless you attack them, and one will tackle you off your mount and eat your face.
